This change is the last part of a three part change for restructing
the root of trust used by the reference implementation.
OEM Certificates are now managed by the root of trust of the crypto
engine. Previously, OEM certs where handled separately on a session
by session basis.

This change is the second part of a three part change for restructing
the root of trust used by the reference implementation.
The use of RSA_shared_ptr has been replaced with the standard library
std::shared_ptr using the RsaPrivateKey wrapper class. The
AuthenticationRoot class now uses this for the built-in DRM cert key.
RSA decryption and signature operations within the session context are
now performed the RsaPrivateKey class. This has reduced the code size
and complexity within the reference and testbed, focusing their
implementation on key policy and less on mechanics.

This change is the first part of a three part change for restructing
the root of trust used by the reference implementation.
The API of the AuthenticationRoot class has been updated to reflect
the OEMCrypto functions that relate to the root of trust. This
involves changing the keybox and DRM Cert methods and adding in new
stubs for OEM Certificates.
The WvKeybox now uses a RAII-like interface to ensure that keyboxes
are provisioned correctly or not at all.

- Public cert getter
- Implements most of OEMCrypto_GetOEMPublicCertificate()
- Certificate validation
- Implements most of OEMCrypto_IsKeyboxOrOEMCertValid() for OEM

This introduces two classes EccPublicKey and EccPrivateKey which
perform all ECC-specific crypto operations. The main operations
required by ECC are:
- Load/serialize keys from/to X.509 DER formats
- Generate ECC signatures
- Verify ECC signatures
- Derive session keys used by other OEMCrypto operations
These new classes still need to be plugged into rest of the reference
OEMCrypto implementation.

Clang and GCC allow for warnings against the arguments for printf-like
functions (e.i. LOGx). These validate that the format type specified
in the format string match the corresponding argument type.
Most of the time, format specifer errors are benign; hence why they
haven't been seen as an error so far. However, with the enabling of
specifier warnings and the enabling of warnings as errors on certain
platforms, these existing errors need to be addressed.
This CL enables format specifier warnings for most of the Widevine
code, with the OEMCrypto L3 implementation which has a single error
which requires a fix in the haystack code before being fixed in the
Widevine branch.
Strict format string warnings are not enabled for non-LP64 systems.

(This is a merge of http://go/wvgerrit/96226.)
This patch does a number of different things in order to re-enable the
CDM to use OpenSSL 1.1.0+ out of the box, instead of just BoringSSL:
* To support https://cryptography.io/, BoringSSL has reimplemented just
enough of the OpenSSL PKCS7 API that we can fulfill our purposes with
code that works on either library. This patch replaces code in
privacy_crypto_boringssl.cpp and oec_session_util.cpp that was only
compatible with BoringSSL with code that also works in OpenSSL.
* Replaces code in oec_session_util.cpp that used the deprecated OpenSSL
1.0.0 API with OpenSSL 1.1.0-compatible code. This code previously
worked on BoringSSL because they have not yet removed the OpenSSL
1.0.0 functions, even though they also implemented the 1.1.0 API.
* Replaces openssl/mem.h (which does not work in OpenSSL 1.1.0 and
higher) with openssl/crypto.h. (which works in all OpenSSL and
BoringSSL releases) This does not require any function code changes.
* The OID-comparison code in privacy_crypto_boringssl.cpp was using
BoringSSL-exclusive functions to convert OBJ-format OIDs to text.
Conversion functions that work on either library exist. However, the
new code uses a different technique instead, pre-converting the
passed-in OID to OBJ format. This allows it to be compared to the
certificate directly, avoiding converting every certificate extension
OID to text.
* Allows the selection of "openssl" as the privacy_crypto_impl and adds
a variable to configure OpenSSL. More will follow in future patches
as more configurations of OpenSSL are supported.

This implements the CDM code changes necessary to take advantage of
Combined Decrypt Calls on OEMCrypto v16. The result of this is that
WVCryptoPlugin is much lighter now because it can pass the full sample
down to the core in one call, but CryptoSession is heavier, as it now
has to handle more complex fallback logic when devices can't handle
multiple subsamples at once.
This patch also removes support for the 'cens' and 'cbc1' schema, which
are being dropped in OEMCrypto v16. This fixes an overflow in the code
for handling those schemas by removing it entirely.
This patch also fixes the "in chunks" legacy decrypt path to use larger
chunk sizes on devices with higher resource rating tiers.
